Option B

Explanation:

The branch of legislative consists of the House of Representatives and the Senate, jointly referred to as Congress. The legislator adopts, among others, all laws, declares war, regulates international and foreign trade and controls tax and expenditure policy. They share with the president, who is usually responsible.
